The middle cap (140) is caught to the upper cap (130) by the upper catching jaw (143) formed its upper end.

The piston (120) of the pumping device (110) is coupled a piston fixing jaw (145) by being interposed the piston catching pipe (142) formed in the middle of the middle cap (140) through a piston insert hole (151) formed in the middle of the lower surface of the bottom cap (150). The piston catching pipe (142) is formed in the middle of the middle cap (140) by the rib (141). On the upper of the piston catching pipe (142), is the pumping pipe (147) interposed to the piston catching (142) and the inner of the piston (120). The pumping hole (149) is formed in the middle of the exhausting pipe (147), and straight inflow groove (148) is formed on the upper of it. The pumping hole (149) is positioned in the middle of the, inflow groove (148).

An inserting bar catching member (133) is formed on one edge of the bottom of the upper cap (130), and an inserting bar (133) is extended to a nozzle groove (131) formed on the opposing edge across the upper end cap (130) after being caught to the inserting bar catching member (133). The inserting bar (132) is inserted into the nozzle (136) so that the opening of the nozzle is blocked. Part of the nozzle (136) is protruded to outside through the nozzle groove (131). Two spring fixing members (134) are formed in the bottom of the upper cap (130) being close to the inflow groove (131), and one end of a first spring (135) is coupled to the spring fixing member (134), respectively. The other end of the first spring (135) is coupled to the upper sliding member (137) disposed in the middle of the upper end cap (130). The upper sliding member (137) and the nozzle (136) are formed integraly. The upper sliding member (137) is contacted with the bottom sliding member (157) formed on the edge of the bottom cap (150). An inlet (138) is formed on the bottom on the nozzle (136), and it is positioned in the inflow groove (148) formed in the pumping pipe (147) but it can be positioned cross with the pumping opening (149).

The pumping device (110) as above mentioned operates as follow. It is clear that the structure of the pumping device (110) from the operation of the pumping device (110) described hereinafter. FIG. 7 a and FIG. 7 b show the operation of the pumping device as a longitudinal sectional view, and FIG. 8 a and FIG. 8 b show the operation of the pumping device as cross sectional view. Also, FIG. 7 a and FIG. 8 a show the condition which the upper cap (130) is not pressed (that is, not used) as a corresponding view each other, and FIG. 7 a and FIG. 8 b show the condition which the upper cap (130) is pressed (that is, used) as a corresponding view each other.

When, the upper cap (130) is not pressed, the upper sliding member (137) and the bottom sliding member (157) are not contacted at their ends each other, the opening of the nozzle (136) is blocked by the inserting bar (132). Accordingly, when the bottle (100) is not used, the nozzle (136) of the cosmetic bottle (100) is always blocked, thus the gel-type contents (104) contained in the nozzle (136) are not contacted to the air outside.

Also, when the upper cap (130) is pressed, the upper sliding member (137) presses the first spring (135) while it slides in contact with the bottom sliding member (157) fixed to the bottom cap (150), and the nozzle (136) formed on the upper sliding member (137) integrally is moved forward. However, the inserting bar (132) is still fixed to the inserting bar catching member (133) of the upper end cap (130). Thus, when the opening of the nozzle (136) is opened, the gel-type contents (104) contained it is pumped to outside.

When the upper cap (130) is pressed, the middle cap (140) caught to the upper cap (130) is pressed toward the bottom. Then, the middle cap (140) presses the second spring (152) and the piston (120) caught to the piston catching pipe (142) simultaneously. The space in the cylinder (114) is diminished and a gap is formed between the piston (120) and the open-close bar (118) according to descending of the piston (120). As result, the hydraulic pressure in the cylinder (114) is higher then the contents in the cylinder (114) are provided to the pumping pipe (147) formed on the upper of the piston (120). Subsequently, the contents provided in the pumping pipe (147) are entered the inlet (138) of the bottom of the nozzle (136) through the pumping hole (147) and the inflow groove (148). As above mentioned, although the nozzle (136) is moved forward and backward, the flow of the contents is not affected because the inlet (138) of the nozzle (136) is moved only in the inflow groove (148) of the pumping pipe (147).

When the force pressing the upper cap (130) is disappeared, the middle cap (140) is ascended to original position by the elastic force of the second spring (152). Thus, the upper cap (130) caught to the middle cap (140) is ascended, and the upper sliding member (137) is retracted to original position by the elastic force of the first spring (135). The nozzle (136) integrally formed on the upper sliding member (137) is also be retracted in backward then the opening of the nozzle (136) is blocked by the inserting bar (132). Also, the piston (120) is ascended simultaneously according to the ascending of the middle cap (140), this the gap between the piston (120) and the open-close bar (118) is clogged. Accordingly, the suction valve (122) is opened while the hydraulic pressure in the cylinder (114) is decreased, and the contents (104) of the main body (102) are provided in the cylinder (114) through the suction pipe (116).

As above described, when the cosmetic bottle using the gel-type cosmetic pumping device according to the present invention, the gel-type contents in the nozzle are cut off from the air in outside because the opening of the nozzle is blocked by the inserting bar. Accordingly, the present invention has an effect that the problem in that the contents are hardened or deteriorated as the prior art is prevented in essence, and it can contribute to improve the reliability of the products.
